Re: "Early Return" - mapping and flatMapping monads does that. If your result type is a monad, you just map or flatMap the success case. That mapping will never execute if the result isn't a success, so it's equivalent to an early return. Several functional languages have special syntax to avoid nesting for sequential flatMapping (e.g. Haskell's do-notation, Scala's for-comprehension) - gleam's "use"-expressions do a version of the same kind of thing: avoid nesting when handling result types.
This does not necessarily solve the same problem - without an early return, you basically have to keep nesting code in your if/else chain (or case, or whatever gleam uses). Early return is usually just an easy way to break out of the function early without having to keep nesting and indenting logic branches.
@@dylan_the_wizard I'm not sure I understand. An early return by definition is inside some form of conditional - you still write code after that (that's what makes it "early"). When it comes to avoiding having to nest code to handle (computations returning) results - that's exactly what Haskell's do-notation and scala's for-comprehension do for monads.
@@DumblyDorrthis isn’t Haskell. If you don’t have early return you need to keep nesting cases. Early return lets you just add more cases underneath instead of indenting to the right.

"Do things that are beautiful", but also "no one cares about your code - all that maters is the result". I can't think of a way to resolve this contradiction if you ONLY code for work... mayby "find beauty in something that you do", instead of "do what you think is beautiful"?
It can easily be resolved if you realize that beautiful code has much fewer bugs. And an important metric for how good 'the result' is, is the number of bugs the system has.
There is a difference between extrinsic and intrinsic motivation. Your extrinsic motivation is to build software your users want to use. Your intrinsic motivation should be to make it beautiful. That's the claim.
@@vinterskugge907 not in my experiance it's not. If I spend my time polishing something to maximum levels of perfection available to me at my current level of proficiency what I usually get is complaints about "what took you so long". If I just slap things together and drop off a commit that barely works - it's fine. As to the bugs - they get delt with if/when they appear and no sooner. As a result, making something "beautiful" is a prerogative I allow myself only when I do things for myself, which the more I work, the less I get the time and/or inclination to do. PS: ...not that there isn't some beauty in jank that boggles the mind as to why and how it manages to do its thing at all ^_^
Of course, types are everything. Types infer methods and it is good when the computer sees what it is working with. You can always pass the right class type to the right function.
3:40 Beauty is just our human brain trying to reward us for what it considers worth of pursuing and attractive. If you do not pursue beauty in your code, you will get burn out very quickly, because nobody likes to work on ugly code. Now, beauty is subjective and it has nothing to do with clean code. Beauty can be a hacky way to achieve something but that hacky way fits so perfectly well that it is beautiful.
Minimal apis arent for scale. Depends on your scope. Theyre all embedded directly into Program.CS so if your program has more than a few CRUD endpoints they instantly lose relevancy. @infinite_s902
@thehumster7837 This reply can't be AI generated because it is full of nonsense. Minimal APIs do not have to be in a single file, they can be anywhere. There is infinite amount of resources talking about minimal APIs being just as scalable as controllers are.
@@ZoneInOn Minimal API setup is just a Map function call from the EndpointRoutes global. There are infintite ways to structure this. You can organize your endpoint resolvers as static classes that include a "MapEndpoints" function so Program.cs just calls into each of those. And if that gets cumbersome you can separate that bit into its own class dedicated to the registration. Alternatively you could do what controllers do and use attributes + reflection to set up any endpoint routes. You could have a separate service dedicated to endpoint resolution that contains all the logic. Etc. etc. The demo examples just call it straight in Program.cs, but the heart of it all is in the IEndpointRouteBuilder.
A Pokemon can only have four moves, so there are at most four queries, and they are run in parallel instead of sequentially since it spawns a task for each call and then waits on all of them with a timeout.
PHP because Laravel. Just get it done. Then when the project has legs it's easy to get more devs at every level and you can peel parts out of the monolith into secondary services if you want to move to other languages within a particular domain (not for scaling, that should already be handled if you've done it right).
Agreed. And honestly, even if u don't use laravel, PHP frameworks in general can do so much stuff so fast to get u up n running. Obviously tho, Laravel is the most robust approach if u need this kind of power

That penguin is an accurate representation of how things work in a lot of projects.

I think we tend to gravitate towards languages that tries to fix languages we've been using, while still be familiar enough with it. I started of coding in Python 6-7 years ago, and even though I have studied Java, C, Haskell in actual classes and even written one or two Rust and Go projects, it never felt "home". I got too accustomed to indentations and multi-paradigm concepts in Python. Recently, I started to use and like nim, and I think it's because it fixes some problems of Python while still being similar enough (at least on the surface, the language has so much more flexibility because of metaprogramming and its ease in making a c wrapper). Anyway that's probably why people switched to JS to TS (without actually switching much) as well... they are used to it and wanted to use something that's better.
Here's the thing. I used to love Java. I also realized it has flaws when looking under the hood. I like OOP, but then I did remember at some point overengineering a class diagram before even doing anything... Kotlin is neat though, but I don't feel like I have excuses to use it as much.
I've stopped trying to fix languages with other languages (I've suffered enough, looking at you, React!). People are the problem, including me. We tend to create what I call "code entropy". This is why I build numerous small C# libraries that each have 1 responsibility. I can tell which packages I use more often based on the version numbers. 😊 And the one with the highest would be my Types nuget package that has extension methods for LINQ, quick null-free string parsing methods (with optinal fallback params), and a special Dump method that prints json to console whenever I'm debugging, but also returns the object so it never breaks control flow or causes eye-bleed. So, basically, for me, 'fixing' my favorite language worked out great for me. I can solve complex problems really fast in LINQ, dive into directories asynchronously with a few keystrokes, debug without stopping or pausing execution, and more odds and ends I'm forgetting because I'm high on coffee ☕️ 😳
Use elixir and build a distributes system, is insane Real-time communication low latency distributed is what elixir shines at. Edit: gleam is another language for the erlang VM, I think is better than elixir in many ways but is just too new still
Gleam needs more dedicated people to build the ecosystem... Or a much stronger standard library. I just don't want to have to write my own everything. I've got kids.
Can you give some examples of how you think that Gleam is better than Elixir in many ways? The only one that I can think of is that Gleam already has static typing whereas Elixir will be getting it a bit later. But it's not like Elixir doesn't have ways to handle most typing errors already (function guards, pattern matching, immutability).
@@Voidstroyer Precisely. Also, lack of metaprogramming in Gleam is a big weakness. The general trend over the past decade has to introduce stronger metaprogramming. An example is how in dire need of metaprogramming Dart is, which it is getting soon; and how their current temporary substitute (build_runner) is messy. C# introduced source-generators. The moment your programing is more than just simple REST APIs, metaprogramming becomes invaluable. I can't imagine something like Phoenix without macros... Literally all languages have adopted metaprogramming to some extent, and Elixir is better than most languages at it. There are so many things that Elixir does much better than Gleam (IMO).
@@balen7555 I agree, however I admit that I have personally not really looked at Gleam as much (just watched a few videos) and so it's possible that my own bias towards Elixir is causing me to not see certain things. Which is why I am curious to see what @siriguillo has to say about his comparison of the two languages. (And to be fair I am curious to see if his opinion is also based on a bias towards Gleam due to lack of knowledge of Elixir).
Occam's razor, the programing community is over represented by people who are both extremely confident and anxious at the same time, this creates this entire bs. No other profession changes tooling, and it's also not needed. If u go full sober no cap, you will see there is hardly any correlation between tools used and the succes of an application. I bet most successful apps are still in wordpress, webflow, php or w/e. Some changes made sense because the world changed, the general introduction of things like bootstrap, vue, react etc. because we went from static text on a single device to interactive on multiple devices, but the differences between them within their tier are not that relevant.
Is it typed to the level of C#? I think TS Is way overtyped (and overhyped), to the point where you're just writing more broken javascript but in a different flavor. But that's a common opinion. Coming from a C# background, I just could not get into TS because I kept falling asleep reading the docs
@@nicholaspreston9586 Elixir is dynamically typed, so like JavaScript without TypeScript, as far as I know. I meant TypeScript as an example for a not that great static type system glued on top of a dynamically typed language. With at least I meant that a type system like C# would be more than the one of TypeScript. :D
Same here. I already know Python and JavaScript. I've done a little Perl and Lisp and that's enough with the dynamic typing languages. Plus Python got type checking and JavaScript has Typescript. What's Elixir got? Fix the type system, and I'll be interested.
Driven by beauty helps you write better code I agree, but it can also drive you down the rabbit hole or give you tunnel vision. You need good discipline to code this way
the whole beauty thing is a bs because it's very egocentric and arbitrary. it's all beautiful until you have to work with someone who has a different concept of beauty and suddenly love turns to hatered because you are forced to do stuff that's ugly (for you). you will do ugly stuff every single day for years because you have to adapt to the environment that has a different notion of what's beautiful. let's call it a tyranny of beauty
Totally agree. Just write boring code that anyone can follow. If you need to explain how your components work together, that’s fine. But if you have to explain how your code works, you might be doing it wrong.
Everyone starting with microservices before they have fully mapped the domain will spend more time on DevOps/Platform engineering tasks than they need to early on. Until there are clear bounded contexts and a compelling reason to use microservices, most early stage projects should use a monolith to start. Early resource investment should be focused on features and delivering product, not technical ideology. End users don't care. The business most likely won't care. The VC/PE money folks won't care. Is your work fit for purpose? Does it add value to the business? Can sales close deals? These are the questions you should be asking early on, not whether the architecture adheres to Reactive/Clean/Onion/DDD/etc. Prioritize tests and working software over pedantic architectural implementations.
First-timers don't mind it slow in the backend if it translates to a softer smoother experience. However, those with more rodeo experience like it fast, and are willing to have it be a bit rough to get the most out of a full performance.
You can tell ThePrimeagen isn't as confident in his position when he gets angry that people suggest something to him. It's gotta be annoying to be pulled in all these different directions. Love the content!
This whole value as errors misses the whole point of exceptions. In another video recently Prime mentions he likes assertions that just fail the app, well that's how you can make exceptions work. If you don't want to handle them. If I'm calling a function X, I don't need to know all the exceptions it potentially might throw, and I don't care, in most cases an exception been thrown is likely something you can't do anything about anyway, (well not easily). eg. Out of memory, out of disk space, file permissions etc etc. But the nice thing if you did want to handle the exception, and implement some sort of recovery you can opt in later. I think a lot of reasons exceptions get bad rep, is when people use them for flow control, if a 3rd party lib is doing this then that's the fault of the lib, not exceptions.
A lot of it also comes from these awful garbage-collected languages where you might end up dropping state if you throw an exception. But that's also not the fault of exceptions, that's the fault of whatever silly person decided to copy the exception model and not also copy RAII to go with it. Exceptions need RAII to work, otherwise you're left in a nightmare scenario where you have to manually catch and cleanup at every level.
@@isodoubIet For resources that require cleanup logic that's a good point. For these the the "finally" comes in, but I think Zig & Go's defer wins here. You could create wrapper function to emulate this, but been built into a language really nice. The main problem with all option here is with them been scope based, a really nice option for a GC language would be closure based cleanup.
@@keithjohnson6510 Yeah it's like that meme "look what they need to mimic a fraction of our power". The "finally" keyword, disposables in C#, context managers in python, defer etc all just feel completely subpar. What do you mean by closure based cleanup?
did you just say effects don't have errors as values? that's kind of the core of it. also soon we'll have effect rotation too so you will not have to wrap everything into an effect.
My only gripe with elixir is the syntax & the type system is primitive (protocols are nice but interfaces are always a welcomed feature in general) & ambiguous at times in my opinion, especially opaque types like socket_handle() in the erlang docs, logically speaking it should be a fd or io_device, however io_device() type is defined as a process ID or an atom (esentially the same thing as a macro, theyre obsessed with atoms & returning tuples from functions, in fact errors are usually tuples where the 0th index is an atom & the 1th index is the errors message?) Overall its better than a couple of languages but its not for me, i do enjoy trying something different tho i wont doubt that, at the end of the day its still programming.
Partition will return a tuple of Ok results and Error results in their own respective lists. For example, [Ok(1), Error("a"), Error("b"), Ok(2)] would return #([2, 1], ["b", "a"])
17:47 It's indeed pretty context specific, so it's not surprising. In gleam it splits a list of results into one list of successes and one list of failures.
@@driyagon well, sort of In functional programming you're encouraged to use recursion (which is a hard concept to grasp in and of itself), then you'll have to think about how to do things in an immutable way and return new copies, how pattern matching works and how to use it effectively, how to make your functions pure (= with no side effects) etc. Functional programming is another paradigm and of course it's not easy to get into, just like you'd struggle as a beginner to understand inheritance, polymorphism and SOLID
to me the function coloring problem seems a lot like a tooling issue. If I have strict typing, it should be possible to automatically refactor all callers to be async and await the call. I think function coloring for async is actually good, particularly if your function only performs async IO sometimes. If you don't know whether a function can block for a long time, its just to easy to accidentally block the main thread of an interactive application, or block shared resources. Having to refactor large parts of you program just because you made a tiny change, is of course annoying, but the solution is automatic refactoring or to explicitly decolor the function (i.e. wrap it in a block_on or whatever your language calls it.)
You can keep Zig, lol. I don't know why I'd build a web app in Zig for allocation reasons, unless it can beat c# or Go. Perhaps it has a niche I'm ignorant of? I mean, it looks cool, but it's on my list of langs to try.
If you do elixir can you talk about how to actually deal with dynamic typing? I always am like "and what is this I'm lost. Tools can't help me. List of list of what? I am in a map and I need to change something in some nesting. Where am I? Fuck it I'm going back to a typed language"
I am so confused about what I just watched. All I got out of this was that there were actors and there were dicts. And talk about how to measure the size of these dicts. I wonder which actor was the one that held the bigger dict.
I wanted to learn a functional language, so I looked at Haskell and OCaml. They were very interesting, but they felt highly alien to me. However, Elixir felt different. Elixir is partially alien, but in a good way. The pervasive use of pattern matching is such a good design, in my opinion. Additionally, Elixir feels really friendly to newcomers. It's really easy to explore new concepts from the functional paradigm, unlike in Haskell where trying to understand what a monad is can be quite challenging ._. Also I consider Elixir being extremely usefull and practical language with some superpowers no other language has (except BEAM langs ofc - Erlang and now Gleam).
Pascal. I know, sounded crazy to me, too, 20 years ago when I switched. But you know what? Still works, and I have yet to meet a developer who doesn't understand it. If there's a bottleneck, the workflow is to use whatever language you want, whatever algorithms you want, just don't change the ABI or API... then, put it in Pascal. Sometimes, fpc makes just as fast an executable, and the bottleneck was algorithmic, so whatever that new language was, usually isn't any faster in a way that improves user-perceived performance. If it is faster, the only comment needed is "see the Pascal". You get a maintainable system, and I know this from watching them exponentially scale for decades without the added cost of buying Kate more pants. Or painting yourself into a corner where "let's just rewrite the whole thing in Rust" actually sounds reasonable. REST, people, not REST API's which are an anti-pattern. HEAS, not HATEOAS, because people are using the latter to describe HTML pages full of identical unclickable buttons. Where are your URIs? Why are you excluding fully 1/3 of the global online population, to make your apps work in a way that won't be valid in five years, forsaking the URL which has an exponential-scaling track record dating back 30 years? THAT is the Web architecture. KISS.
I don't code in Haskell, but these projects, ghc comes in 2nd to fpc, and is the exception to the above, because there is no direct algorithmic translation from Haskell to... well, to anything. But where a recursive functional algorithm is called for, ghc has a userspace threading model that really kicks, and by using Pascal and Haskell... where's the vendor lock-in? The incessant changes? The failure to maintain backwards compatibility with 20-year-old code? OK, Haskell developers are hard to come by, but not for these projects. Several Forbes 500's in a common niche adopted my system for interoperability, but I'm under an NDA although they rarely consult me anymore.
I'm also considering doing backends in FP, what do you use nowadays? Are you straight up using fpweb or do you use something like Fano/Brook? I'm actually curious to see your opinion.
@@stefanalecu9532 I ranch nowadays. I get called in once a year to explain how REST APIs are no more REST than Tesla's thingie is a truck, so I don't know if they're using fpweb, probably not, although it's the same design pattern. All the httpd needs to know is FCGI, all the backend apps need to know is FCGI. We take this a step further by putting those apps in Zones or Jails with no network stack, POSIX IPC for the FCGI win. On the front end, HTTP 1.1 pipelining. No plans to upgrade to 3 any more than 2, no need to suck. No streaming videos, those are on Vimeo.
httpd only passes requests to the app when the cache expires, gets the Atom file back, writes it to disk, and now it's cached until it needs to be changed again, last-modified and etag are just filesystem metadata. The apps aren't doing anything unless they need to, the webserver's on autopilot, and the user-perceived performance isn't giving back the paltry latency gains of this century. It's about the latency. Over 30 years, only 30% improvement. Compare that to CPU/RAM/storage gains, and treat it as a precious commodity.
The user who sends a change of application state to the server, is the user who makes the first request for that new application state, no? How long does it take, when you e-mail a reply to a listmail, for it to reflect? A few seconds? Do you care? That's why I say back-end performance really doesn't matter, because the architectural style means that latency disappears for subsequent requests, until the application state is changed. But, it's always nice to reduce that first-request latency. Just not a critical concern, so use whatever coding language you want. Those details are hidden behind uniform interfaces all the way, i.e. HTTP and FCGI. But on that first request to the posting user, precision is the concern over performance. Input sanitization and validation, takes how long it takes.

"More microservices than users" 😂ok that made me laugh out loud.
Re: "Early Return" - mapping and flatMapping monads does that. If your result type is a monad, you just map or flatMap the success case. That mapping will never execute if the result isn't a success, so it's equivalent to an early return. Several functional languages have special syntax to avoid nesting for sequential flatMapping (e.g. Haskell's do-notation, Scala's for-comprehension) - gleam's "use"-expressions do a version of the same kind of thing: avoid nesting when handling result types.
where can we learn more?
C'MON, MAN! Don't leave me hanging!!!
This does not necessarily solve the same problem - without an early return, you basically have to keep nesting code in your if/else chain (or case, or whatever gleam uses). Early return is usually just an easy way to break out of the function early without having to keep nesting and indenting logic branches.
@@dylan_the_wizard I'm not sure I understand. An early return by definition is inside some form of conditional - you still write code after that (that's what makes it "early").
When it comes to avoiding having to nest code to handle (computations returning) results - that's exactly what Haskell's do-notation and scala's for-comprehension do for monads.
@@DumblyDorrthis isn’t Haskell. If you don’t have early return you need to keep nesting cases. Early return lets you just add more cases underneath instead of indenting to the right.
Sometimes when Prime talks a lot and seemingly with a lot of conviction about something I feel like what is actually happening is that he's trying to convince himself about what he is saying.
Nah, it's your insecurities poking their noses. Projecting your own uncertainties with his convictions being a sign of his lack of confidence.

"Do things that are beautiful", but also "no one cares about your code - all that maters is the result". I can't think of a way to resolve this contradiction if you ONLY code for work... mayby "find beauty in something that you do", instead of "do what you think is beautiful"?
Yea, if I brought elixir or gleam into my next project at work I'd be crucified
you are taking this too literally, the idea is more "do a beautiful project", something that can help others, etc...
It can easily be resolved if you realize that beautiful code has much fewer bugs. And an important metric for how good 'the result' is, is the number of bugs the system has.
There is a difference between extrinsic and intrinsic motivation.
Your extrinsic motivation is to build software your users want to use. Your intrinsic motivation should be to make it beautiful. That's the claim.
@@vinterskugge907 not in my experiance it's not. If I spend my time polishing something to maximum levels of perfection available to me at my current level of proficiency what I usually get is complaints about "what took you so long". If I just slap things together and drop off a commit that barely works - it's fine. As to the bugs - they get delt with if/when they appear and no sooner.
As a result, making something "beautiful" is a prerogative I allow myself only when I do things for myself, which the more I work, the less I get the time and/or inclination to do.
PS: ...not that there isn't some beauty in jank that boggles the mind as to why and how it manages to do its thing at all ^_^
Of course, types are everything. Types infer methods and it is good when the computer sees what it is working with. You can always pass the right class type to the right function.
3:40 Beauty is just our human brain trying to reward us for what it considers worth of pursuing and attractive.
If you do not pursue beauty in your code, you will get burn out very quickly, because nobody likes to work on ugly code.
Now, beauty is subjective and it has nothing to do with clean code. Beauty can be a hacky way to achieve something but that hacky way fits so perfectly well that it is beautiful.

It’s pretty simple tbh
Specially the minimal api
Minimal apis arent for scale. Depends on your scope. Theyre all embedded directly into Program.CS so if your program has more than a few CRUD endpoints they instantly lose relevancy. @infinite_s902
@thehumster7837 This reply can't be AI generated because it is full of nonsense. Minimal APIs do not have to be in a single file, they can be anywhere. There is infinite amount of resources talking about minimal APIs being just as scalable as controllers are.
+1, quick setup and there’s not much you cannot do without too much finagling
@@ZoneInOn Minimal API setup is just a Map function call from the EndpointRoutes global. There are infintite ways to structure this. You can organize your endpoint resolvers as static classes that include a "MapEndpoints" function so Program.cs just calls into each of those. And if that gets cumbersome you can separate that bit into its own class dedicated to the registration. Alternatively you could do what controllers do and use attributes + reflection to set up any endpoint routes. You could have a separate service dedicated to endpoint resolution that contains all the logic. Etc. etc. The demo examples just call it straight in Program.cs, but the heart of it all is in the IEndpointRouteBuilder.

I think we tend to gravitate towards languages that tries to fix languages we've been using, while still be familiar enough with it.
I started of coding in Python 6-7 years ago, and even though I have studied Java, C, Haskell in actual classes and even written one or two Rust and Go projects, it never felt "home". I got too accustomed to indentations and multi-paradigm concepts in Python. Recently, I started to use and like nim, and I think it's because it fixes some problems of Python while still being similar enough (at least on the surface, the language has so much more flexibility because of metaprogramming and its ease in making a c wrapper).
Anyway that's probably why people switched to JS to TS (without actually switching much) as well... they are used to it and wanted to use something that's better.
Try harder with java, you'll notice. And you'll think about all the python devs, that they are the result of a failed school system
Here's the thing. I used to love Java. I also realized it has flaws when looking under the hood. I like OOP, but then I did remember at some point overengineering a class diagram before even doing anything...
Kotlin is neat though, but I don't feel like I have excuses to use it as much.
I've stopped trying to fix languages with other languages (I've suffered enough, looking at you, React!). People are the problem, including me. We tend to create what I call "code entropy". This is why I build numerous small C# libraries that each have 1 responsibility. I can tell which packages I use more often based on the version numbers. 😊
And the one with the highest would be my Types nuget package that has extension methods for LINQ, quick null-free string parsing methods (with optinal fallback params), and a special Dump method that prints json to console whenever I'm debugging, but also returns the object so it never breaks control flow or causes eye-bleed.
So, basically, for me, 'fixing' my favorite language worked out great for me. I can solve complex problems really fast in LINQ, dive into directories asynchronously with a few keystrokes, debug without stopping or pausing execution, and more odds and ends I'm forgetting because I'm high on coffee ☕️ 😳

Elixir is the most readable functional language there is, which isn't much to say, but hey, at least its something
Use elixir and build a distributes system, is insane
Real-time communication low latency distributed is what elixir shines at.
Edit: gleam is another language for the erlang VM, I think is better than elixir in many ways but is just too new still
Gleam needs more dedicated people to build the ecosystem... Or a much stronger standard library.
I just don't want to have to write my own everything. I've got kids.
I prefer Elixir over Gleam in every way possible. And Elixir is getting an interesting type system too.
Can you give some examples of how you think that Gleam is better than Elixir in many ways? The only one that I can think of is that Gleam already has static typing whereas Elixir will be getting it a bit later. But it's not like Elixir doesn't have ways to handle most typing errors already (function guards, pattern matching, immutability).
@@Voidstroyer Precisely. Also, lack of metaprogramming in Gleam is a big weakness. The general trend over the past decade has to introduce stronger metaprogramming. An example is how in dire need of metaprogramming Dart is, which it is getting soon; and how their current temporary substitute (build_runner) is messy. C# introduced source-generators.
The moment your programing is more than just simple REST APIs, metaprogramming becomes invaluable. I can't imagine something like Phoenix without macros...
Literally all languages have adopted metaprogramming to some extent, and Elixir is better than most languages at it.
There are so many things that Elixir does much better than Gleam (IMO).
@@balen7555 I agree, however I admit that I have personally not really looked at Gleam as much (just watched a few videos) and so it's possible that my own bias towards Elixir is causing me to not see certain things. Which is why I am curious to see what @siriguillo has to say about his comparison of the two languages. (And to be fair I am curious to see if his opinion is also based on a bias towards Gleam due to lack of knowledge of Elixir).
Occam's razor, the programing community is over represented by people who are both extremely confident and anxious at the same time, this creates this entire bs. No other profession changes tooling, and it's also not needed. If u go full sober no cap, you will see there is hardly any correlation between tools used and the succes of an application. I bet most successful apps are still in wordpress, webflow, php or w/e.
Some changes made sense because the world changed, the general introduction of things like bootstrap, vue, react etc. because we went from static text on a single device to interactive on multiple devices, but the differences between them within their tier are not that relevant.

I would take a look at Elixir, if it where statically typed. At least at the level of TypeScript.
Is it typed to the level of C#? I think TS Is way overtyped (and overhyped), to the point where you're just writing more broken javascript but in a different flavor. But that's a common opinion. Coming from a C# background, I just could not get into TS because I kept falling asleep reading the docs
@@nicholaspreston9586 Elixir is dynamically typed, so like JavaScript without TypeScript, as far as I know. I meant TypeScript as an example for a not that great static type system glued on top of a dynamically typed language. With at least I meant that a type system like C# would be more than the one of TypeScript. :D
Same here. I already know Python and JavaScript. I've done a little Perl and Lisp and that's enough with the dynamic typing languages. Plus Python got type checking and JavaScript has Typescript. What's Elixir got? Fix the type system, and I'll be interested.
Id use Spring, probably. I just like the batteries included thing.
Driven by beauty helps you write better code I agree, but it can also drive you down the rabbit hole or give you tunnel vision. You need good discipline to code this way
the whole beauty thing is a bs because it's very egocentric and arbitrary. it's all beautiful until you have to work with someone who has a different concept of beauty and suddenly love turns to hatered because you are forced to do stuff that's ugly (for you). you will do ugly stuff every single day for years because you have to adapt to the environment that has a different notion of what's beautiful. let's call it a tyranny of beauty
Totally agree. Just write boring code that anyone can follow. If you need to explain how your components work together, that’s fine. But if you have to explain how your code works, you might be doing it wrong.
Beautiful code comes from experience and if you don't have experience then you will write bad code even when you don't try to write beautiful code
Everyone starting with microservices before they have fully mapped the domain will spend more time on DevOps/Platform engineering tasks than they need to early on. Until there are clear bounded contexts and a compelling reason to use microservices, most early stage projects should use a monolith to start. Early resource investment should be focused on features and delivering product, not technical ideology. End users don't care. The business most likely won't care. The VC/PE money folks won't care. Is your work fit for purpose? Does it add value to the business? Can sales close deals? These are the questions you should be asking early on, not whether the architecture adheres to Reactive/Clean/Onion/DDD/etc. Prioritize tests and working software over pedantic architectural implementations.
First-timers don't mind it slow in the backend if it translates to a softer smoother experience. However, those with more rodeo experience like it fast, and are willing to have it be a bit rough to get the most out of a full performance.
You can tell ThePrimeagen isn't as confident in his position when he gets angry that people suggest something to him. It's gotta be annoying to be pulled in all these different directions. Love the content!
That's why Ruby on rails is best option for start-ups, you just deliver as much features as possible
This whole value as errors misses the whole point of exceptions. In another video recently Prime mentions he likes assertions that just fail the app, well that's how you can make exceptions work. If you don't want to handle them. If I'm calling a function X, I don't need to know all the exceptions it potentially might throw, and I don't care, in most cases an exception been thrown is likely something you can't do anything about anyway, (well not easily). eg. Out of memory, out of disk space, file permissions etc etc. But the nice thing if you did want to handle the exception, and implement some sort of recovery you can opt in later. I think a lot of reasons exceptions get bad rep, is when people use them for flow control, if a 3rd party lib is doing this then that's the fault of the lib, not exceptions.
A lot of it also comes from these awful garbage-collected languages where you might end up dropping state if you throw an exception. But that's also not the fault of exceptions, that's the fault of whatever silly person decided to copy the exception model and not also copy RAII to go with it. Exceptions need RAII to work, otherwise you're left in a nightmare scenario where you have to manually catch and cleanup at every level.
@@isodoubIet For resources that require cleanup logic that's a good point. For these the the "finally" comes in, but I think Zig & Go's defer wins here. You could create wrapper function to emulate this, but been built into a language really nice. The main problem with all option here is with them been scope based, a really nice option for a GC language would be closure based cleanup.
@@keithjohnson6510 Yeah it's like that meme "look what they need to mimic a fraction of our power". The "finally" keyword, disposables in C#, context managers in python, defer etc all just feel completely subpar. What do you mean by closure based cleanup?
did you just say effects don't have errors as values? that's kind of the core of it. also soon we'll have effect rotation too so you will not have to wrap everything into an effect.
4:06 What amazing wisdom
My only gripe with elixir is the syntax & the type system is primitive (protocols are nice but interfaces are always a welcomed feature in general) & ambiguous at times in my opinion, especially opaque types like socket_handle() in the erlang docs, logically speaking it should be a fd or io_device, however io_device() type is defined as a process ID or an atom (esentially the same thing as a macro, theyre obsessed with atoms & returning tuples from functions, in fact errors are usually tuples where the 0th index is an atom & the 1th index is the errors message?)
Overall its better than a couple of languages but its not for me, i do enjoy trying something different tho i wont doubt that, at the end of the day its still programming.
In Plankalkül , of course.

Partition will return a tuple of Ok results and Error results in their own respective lists. For example, [Ok(1), Error("a"), Error("b"), Ok(2)] would return #([2, 1], ["b", "a"])

@@FirstYokai so are there design principles and stuff for writing functions? what makes it difficult to follow?
@@driyagon well, sort of
In functional programming you're encouraged to use recursion (which is a hard concept to grasp in and of itself), then you'll have to think about how to do things in an immutable way and return new copies, how pattern matching works and how to use it effectively, how to make your functions pure (= with no side effects) etc. Functional programming is another paradigm and of course it's not easy to get into, just like you'd struggle as a beginner to understand inheritance, polymorphism and SOLID
@@stefanalecu9532 oh wow okay. i should probably look at some functional projects to understand how to write good functional code. thanks a lot!
to me the function coloring problem seems a lot like a tooling issue. If I have strict typing, it should be possible to automatically refactor all callers to be async and await the call.
I think function coloring for async is actually good, particularly if your function only performs async IO sometimes. If you don't know whether a function can block for a long time, its just to easy to accidentally block the main thread of an interactive application, or block shared resources.
Having to refactor large parts of you program just because you made a tiny change, is of course annoying, but the solution is automatic refactoring or to explicitly decolor the function (i.e. wrap it in a block_on or whatever your language calls it.)

elixir mentioned.. let's gooo
Huge gold nugget at the end of the video!
watching your videos make me feel like I'm a beginner
If you do elixir can you talk about how to actually deal with dynamic typing? I always am like "and what is this I'm lost. Tools can't help me. List of list of what? I am in a map and I need to change something in some nesting. Where am I? Fuck it I'm going back to a typed language"
Good video.
Now let's watch it.
I am so confused about what I just watched. All I got out of this was that there were actors and there were dicts. And talk about how to measure the size of these dicts. I wonder which actor was the one that held the bigger dict.
I wanted to learn a functional language, so I looked at Haskell and OCaml. They were very interesting, but they felt highly alien to me. However, Elixir felt different. Elixir is partially alien, but in a good way. The pervasive use of pattern matching is such a good design, in my opinion. Additionally, Elixir feels really friendly to newcomers. It's really easy to explore new concepts from the functional paradigm, unlike in Haskell where trying to understand what a monad is can be quite challenging ._.
Also I consider Elixir being extremely usefull and practical language with some superpowers no other language has (except BEAM langs ofc - Erlang and now Gleam).

Pascal. I know, sounded crazy to me, too, 20 years ago when I switched. But you know what? Still works, and I have yet to meet a developer who doesn't understand it. If there's a bottleneck, the workflow is to use whatever language you want, whatever algorithms you want, just don't change the ABI or API... then, put it in Pascal. Sometimes, fpc makes just as fast an executable, and the bottleneck was algorithmic, so whatever that new language was, usually isn't any faster in a way that improves user-perceived performance. If it is faster, the only comment needed is "see the Pascal". You get a maintainable system, and I know this from watching them exponentially scale for decades without the added cost of buying Kate more pants. Or painting yourself into a corner where "let's just rewrite the whole thing in Rust" actually sounds reasonable. REST, people, not REST API's which are an anti-pattern. HEAS, not HATEOAS, because people are using the latter to describe HTML pages full of identical unclickable buttons. Where are your URIs? Why are you excluding fully 1/3 of the global online population, to make your apps work in a way that won't be valid in five years, forsaking the URL which has an exponential-scaling track record dating back 30 years? THAT is the Web architecture. KISS.
I don't code in Haskell, but these projects, ghc comes in 2nd to fpc, and is the exception to the above, because there is no direct algorithmic translation from Haskell to... well, to anything. But where a recursive functional algorithm is called for, ghc has a userspace threading model that really kicks, and by using Pascal and Haskell... where's the vendor lock-in? The incessant changes? The failure to maintain backwards compatibility with 20-year-old code? OK, Haskell developers are hard to come by, but not for these projects. Several Forbes 500's in a common niche adopted my system for interoperability, but I'm under an NDA although they rarely consult me anymore.
I'm also considering doing backends in FP, what do you use nowadays? Are you straight up using fpweb or do you use something like Fano/Brook? I'm actually curious to see your opinion.
@@stefanalecu9532 I ranch nowadays. I get called in once a year to explain how REST APIs are no more REST than Tesla's thingie is a truck, so I don't know if they're using fpweb, probably not, although it's the same design pattern. All the httpd needs to know is FCGI, all the backend apps need to know is FCGI.
We take this a step further by putting those apps in Zones or Jails with no network stack, POSIX IPC for the FCGI win. On the front end, HTTP 1.1 pipelining. No plans to upgrade to 3 any more than 2, no need to suck. No streaming videos, those are on Vimeo.
httpd only passes requests to the app when the cache expires, gets the Atom file back, writes it to disk, and now it's cached until it needs to be changed again, last-modified and etag are just filesystem metadata. The apps aren't doing anything unless they need to, the webserver's on autopilot, and the user-perceived performance isn't giving back the paltry latency gains of this century.
It's about the latency. Over 30 years, only 30% improvement. Compare that to CPU/RAM/storage gains, and treat it as a precious commodity.
The user who sends a change of application state to the server, is the user who makes the first request for that new application state, no?
How long does it take, when you e-mail a reply to a listmail, for it to reflect? A few seconds? Do you care? That's why I say back-end performance really doesn't matter, because the architectural style means that latency disappears for subsequent requests, until the application state is changed.
But, it's always nice to reduce that first-request latency. Just not a critical concern, so use whatever coding language you want. Those details are hidden behind uniform interfaces all the way, i.e. HTTP and FCGI. But on that first request to the posting user, precision is the concern over performance. Input sanitization and validation, takes how long it takes.

Please do that for the rest of your career.
The one thing I liked about Web Services from the SOAP era was WSDL files. Just download the thing and generate the client. Something like this should be mandatory for every API.
There's Open API spec for APIs now and you can generate clients from them.
There is OpenAPI 3.0 and AsyncAPI which will generate clients for you.
RPC frameworks do that.
